Hello, I have measured two point clouds of the same plane in x,y,z-format. One is the reference and one point cloud that I want to examine.
The goal is to determine the average error between the reference and the second point cloud.
here is the reference: ROT_4M_0_0
and here is the second point cloud: Rot_4m_0_0
I tried fitting methods like
pcfitplane
or
fit
, to reduce scattered points and then I wanted to compare those two clouds. But it seems like there is no way, where you can use one cloud as a reference.
Thanks in advance for your help.

I assume that you mean extracting and comparing features between the two point clouds. You can achieve by using the extractFPFHFeatures function to extract the features and the pcmatchfeatures function to find matching features between both of the point clouds.
